To @ZZ 'whom t may concern.'

e i mown ia Liso n aci z B tl tltLC Piero, tien Y ofthe United States, residing at Falun, in

the county of Saline and State of lansas, have invented certain new and useful lmprovements in VVindow-Locks, ot which the following is a specification, reference being had to the accompanying drawings.

This invention relates to locks and latches, and particularly to means for locking window sashes.

The general object of the invention is to provide an extremely'rsimple device oi' this character which isreadily operated,-which will positively hold the windowsash `from upward movementk when the window sash is locked, and which is concealed so thatV only thel operating knob shows. o

Other objects will appearv in the course of the following description.

n My invention is illustrated in the accompanying drawings, wherein -v Figure 1 is a sectional view of a window casing and a portion of a window sash showing my window lock applied thereto; Fig. 2 is a horizontal section of Fig. 1, the section being taken through the barrel forming the bolt casing;

` Fig. 3 is a fragmentary race elevation oi a window and window casing showing the lock in place in dotted lines.

Referring'to these drawings, 10 designates a base plate having screw holes at the corners, whereby it may be attached to the woodwork of the window casing.

vRiveted or otherwise. attached to the base plate is a tubularbarrel 12, open at its opposite ends and formed with a longitudinally extendingislot 13. Disposed within thisl tubular barrel is a bolt 14 having-a lug or pin 15 projecting out through theslot 13, and this pin extends throughY a slot in the extremityy of a lever or arm 16 which is carried vby a rotatable shaft or pin 17, this pin or rshaft 17 being rotatably mountediin the plate 10 and proiecting out therefrom and through the casing of the window, :as illustrated in Fig. 2. The exterior face of this pin is provided with a knob 18, and by rotating this knob the bolt is shifted inward or outward. The words Locked and Unlockedr7 are adapted to be applied to the window, as indicated in the drawings, so as t0 indicate whether the latch is projected or retracted. The knob is `made removable from the extremityy of the shaftA 1.7 so that the device may be placed in position or removed.. rlhe casing is put in place,

the shaft 1.7 extended through the opening in the casing, and the knob attached.

I claim l. The combination ywith a window casing anda sash operating therein, of means .for locking the sash including a base, an

ing a pin projecting out through the slot,.

a lever pivotally mounted on the base plate and having ashaft extending outward from the base plate at its axis, and a detachable knob attached to said shaft.

Intestimony whereof I hereunto aiiix my signature. o
